, is claims. This Vinvention relates to wrapping machines,

and more particularly automaticmachines for the matic wrapping machine`in which the feed Lor,

travel of a series or procession of the articles to be wrapped, and aprocession of wrapping sheets therefor, and the application and securingof the wrapping sheetsto the articles, are effected with eiiicientcooperation during continuous 'travel or advance so as to deliver at thedischarge end a series of completely wrapped and secured articles. vAnother object is to afford a wrapping machine through which thearticle, the wrapping sheet, and the wrapped article, advance not onlywith continuous travel, the operations performed while in vmotion, butalong a. straight line of feed or travel, the `article. entering themachine at the infeed end and advancing straightly. and horizontallythrough the machine for discharge in the same straight line of travel,therebyV permitting high rate of operation.

A further object is to afford an open vconstruction of machine -Ainwhich the several operations are'in plain view, and theoperating partsreadily accessible for purposes of adjustment and repair or for' theremoval of books or wrappers in case of defective operation.

,Further objects include the provision of specie mechanisms forperforming the successive operationsvon the article or book and thesheet or wrapper as will be herein described.

Other and more particular objects and advantages' of 'the invention willbe explained in the hereinafter following description of an illustrative-embodiment thereof or will be understood by thoseconversant with thesubject. To the attainment of such objects and advantages the presentinvention consists in the novel wrapping machine and the novel featuresof operation,

'I'he illustrated 'wrapping machine shown in thek drawings may bevconsidered as operating upon pamphlets or other books B in theneighlarge number of wrapped books per minute. The

books are shown as advancing edgewise, that is, standing in a verticalplane and moving through the machine in said plane, and preferably thebooks -travel with the back edges downward and their front or open edgesupward, and in quite the right portions of the machine.

close succession since all of the operations are substantiallycontinuous.

Various adjustments fordifferences in thickness of book will beunderstood, and adjustments also for differences in width of book, thatis the vertical dimension thereof when traveling through the machine.The horizontal length of the traveling books is of no consequenceexcepting that shorter books may be fed in more frequently than longerones, namely, by speeding up the travel and the infeed of books andwrappers, and changing if necessary the -spacing of the feeding lugs orpins, as on the wrapper conveyor chain. In any case the'infeed of thewrappers to the succession books is to be'carefully synchronized by thetiming and adjustment of the action. 'Certain adjustments are shown forvariations in book dimension and analogous ones will be understood wherenot' shown. v

Referring rst to some of the general parts, above a common base 20 isshown a system of columns 2| carrying a first or left table 22 and asecond or main or right table 23, supporting respectively the mechanismsat the left and at At the extreme right end is a column carrying theoperative parts at that end of the machine. At the extreme left, uponthe base 20, is shown the frame 21 of a wrapper supplying mechanism,conventionally shown as a sheet feeder, but which might supply wrappersfrom a roll of paper, fed advancingly and severed in a well knownmanner. In the lower part of the machine turning in the columns 2| isshown the longitudinal main l shaft which may be driven continuouslythrough a gear 3| carried on the shaft and meshing with a pinion 321 onthe shaft of a drive motor 33.

The books B, with their back edges downward, may be supplied from timeto 'time to a hopper shown in Figs. l and le, having a slanting bottomto bring the books successively to their lower front position in theline of feed, where they are stopped and registered by a vertical frontwall 36, the right wall 31 of the hopper being adjusted or cut away topermit a single book at a time to be thrust rightwardly fr om the hopperto the feeding or conveying devices.

reciprocating pusher 39 moving in harmony with the; rest of the machine,operating to push each foremost 'book rightwardly from the hopper andthen: to return for the next/succeeding book. Af

pair of opposite initial feed rolls 40 is shown arranged to grip theopposite sides of each book when thrust partlyfrom the hopper, theserolls being upon vertical shafts 4| turned by belts 42 so that each bookis gripped and driven forwardly lto .the conveying means to bedescribed; the belts shown 'carried on left and right brackets 434 and44 mounted above the table 22. The conveyor.

consists primarily of a system of opposite feed Any conventional feedermay be employed, and there is indicated a belts 45, there being shownthree at each sid of the book path, at three different elevations, an ofthree different lengths, so as to accommodat the wrapper handlingdevices while maintaining maximum control of the book travel. The belt45, for example, may berubberized V-belts traveling in the V-grooves ofthree pairs of pulleys 46 at the right and three pairs of pulleys 41 atthe left, the construction and arrangement being thus shown in Figs. l,4 and 5.

For driving the front set of V-belts the front system of pulleys 41 isshown mounted on a vertical front shaft 48 mounted in the bracket 43 andhaving at its top end a bevel gear 49 engaging a bevel gear 50 on ahorizontal shaft 5| which carries a sprocket wheel driven by asprocketchain 52 from a sprocket wheel 53 on a cross shaft 54 near thebase of the machine, thecross shaft carrying a Worm wheel 55 driven by aworm 56 on the drive shaft 30. The speed of the main shaft and theratios of the described gear train may be suchfx for example, as toadvance the conveyor belts 200 feet per minute, for a travel at thatspeed of the procession of books. The drive of the rear set of V-belts45 .will be later described.

An adjustment is shown for altering the spacing between the frontconveyor belts 45 and the corresponding rear belts, to accommodate booksof varying thickness. As seen in Figs. 4 and 5, the front belts andtheir pulleys 46 and 41 are mounted on a fixed longitudinal carriage 51on brackets 43 and '44, while the corresponding rear parts are mountedon an adjustably slidable carriage 58, supported beneath the overheadportion of the bracket 44, the carriage 58 having parts overlying theedge or ange of the bracket for the rigid holding and guidance thereof.The adiustment of the rear carriage 58 and all the parts carried by itmay be readily effected by means of a threaded adjusting shaft 59turning in a threaded part of the carriage 58 and extending forwardly towhere the shaft is provided with a crank or handle 68 by which it may beturned for changing the adjustment.

For driving the rear set of belts 45 in any adiustment the left handpulleys 41 of the rear belts are mounted on a common vertical rear shaft6|, similar to the front shaft 48 but turning on the carriage 58. Inorder to transmit rotary motion from the front shaft 48 to the rearshaft 8| the front shaft is shown provided with a gear 62, and above thegear, as seen in Fig. 1, a radius arm 63. A similar radius arm 64extends from the shaft 6|. below the gear, and at the junction of thetwo radius arms there is pro. vided an idler gear 65. Between the gear62 and the gear is a reversing pinion 66, mounted on Varm 63, while thegear 65 meshesA directly with a gear 61 o'n the shaft 6I. This geartrain maintains constant connection so that the gears 62 and 61 rotatecontinuously in opposite directions, to drive the inner stretches of the'respective conveyor belts 45- in the same advancing direction.

The active or inner stretches of the belts 45, where they travel alongthe carriages 51 and 58, are shown engagedby grooved idler pulleya 63mounted on the carriages, and each of these pulor cushion means pressingthe pulley and thereby the belt inwardly against the side of the book.A1so, each of the vbelts 45, at its outer stretch, may

be engaged by a grooved tension pulley 10 which may be Set. as shown inFig. 4, in a position to conveying-,side belts 45 and upon an underneathconveyor belt 15 as shown in'Figs. 1 and 5. This belt supports the booksubstantially to the diagonal wrapper applying belt(||3 to be described.

be driven by the means which feeds the wrappers to the belt. Thus anidler pulley 8| is shown below the pulley 18 and a belt or sprocketchain 82 is shown as traveling around thedrums 16 and 18 or adjacentsprocket wheels to the pulley 8| and thence around a pulley 83 adjacentto the wrapper supply. On the same shaft with the pulley or sprocketwheel 83 is shown a smaller sprocket wheel 84. To the left of theseparts is a wrapper feed pulley 85 and this carries a smaller sprocketwheel 86 which operates through a sprocket chain 81 to drive thesprocket wheel 84 and thereby the wheel 83 and connected system. v"Thesprocket i wheel 8S.in turn is driven through a'sprocket chain 89 from asprocket wheel on the cross` shaft 54 already mentioned. Feed belts 9|are shown passing around the pulleys 83 and 85 for the purpose of.conveying wrappers singly to the wrapper conveying chain 82. Idlers ordrop rollers 92-I ensure friction engagement4 of-the wrappers upon i thebelts' 9|. i

The supply of wrapping sheets W is shown accommodatedr in a hopper 93which may be provided in any conventionallmanner with a separatingdevice to detach. the lowermost sheet and an extractor device to pullthe sheet out and cause it to advance along the belts 9| and thence thesprocket chains 82. Said sprocket chains are shown provided withupstanding pushers or pins 91 spaced apart the correct distance to feedthe successive wrappers along an upslanting path from the supply to theunder belt 15, whereon each Wrapper meets an infed book from the bookhopper 35, the two thence passing along together through thef machineunder the control of the preliminary and main ing devices or belts.

-It is desirableI that each wrapper shouldl be scored by two score markscorresponding with the width of the back of the book and this is shcwnaseffected during the upslanting travel -of the wrapper as carried by thechains 82. As

seen in Figs. 1 and 1b a pair of scoring 'disks 99 'is mountedadjustably on av shaft |00 opposite to a resilient or rubber roller |l.The end of the shaft |00, carries a sprocket wheel |02 and the end ofthe corresponding shafti of the roller 0| carries a sprocket wheel |03and these sprocket wheels are `shown as connected by sprocket chains |04and |05 respectively with' sprocket wheels mounted on the same shaftwith the pulley 83, so that the power drive is transmitted to turn allof the described parts in unison at equivalent speeds. ,The score marksor creases facilitate the later shaping of the -wrapper to the book. Thescoring of the wrapper may be done by la device pressing intermittentlyupon the paper similar tothestraight edge device |60 and its operatingconnections described below..

The book B and wrapper W havingnow been assembled, and being inadvancing travel toward the right, are subject to a series of operationsincluding, rst, the upward folding and .from the other to accommodategroups 0f Convey--` smoothing of the wrapper -against the'opposite sidefaces of tle book, forming the two wrapper portions or flaps, namelyrear flap W', which is to be folded over enclosingly for sealing byherein appropriately scored to facilitate their The belt l is shownpassing arounda left or pulley 18 turning on a shaft 11 and a right-,drum 18 turning on a shaft 19. The belt 15 may folded over and downinto adhering contact lwith the front ap' of the wrapper and finallysqueezing pressure is applied to cause the adhesive to seal the product,the product then being discharged upon a conventional or otheroutfeeding receptacle, all these operations occurring during advancingtravel.

The means for upfolding the opposite por-l tions of the Wrapper is bestshown in Figs.'1, 5,

6 and 7.' First the oppositev sides vof the wrapper are subjected to a.preliminary lifting action by means of upslanting front and rear walls.

||0, partly lifting the wrapper flaps, .as seen Iin Fig. 5, the rearwall |0-having a wing nut or similar-means for adjusting the spacingbooks of varying thickness. The wrapper flaps lW," and W2 being thuspartly lifted are ready Ito be acted upon by the diagonal folding andsmoothing .belts 3 acting progressively and oppositely against eachadvancing book. Each of the opposite belts ||3 is shown aspassing arounda lower pulley 4 and an upper pulley ||5, these pulleys being attachedto short shafts turning in an inclined bracket ||6 fixed at the top of abase piece |1 mounted upon the frame table 23. The plan of this part ofthe invention is to drive the inclined belts ||3 at such speed thattheir forward component of motion equals the advancing speed of travel'of the books. The drive may 'be effected through a pulley H8 on theshaft of I the lower front pulley 4, this being connected by a belt ||9with a pulley |20 mounted on an inclined lshaftfnear the base of themachine, the shaftcarrying also a helical gear |2| turned by acorresponding gear on the cross shaft 54. Similar connections maybe usedfor driving the rear belt ||3,'oritv may be driven from` the other bycommunicating gearing. v v 1 By these wrapper upfolding and smoothingdevices ||0, ||3,'the`opposite flaps ofthe wrapper,

,which have already been defined -by the scoring previously performed,4are progressively cswung up and 'folded in against the sides of thebook. It is quite importantthat the sides of the wrapper shall besnugly, and smoothly `pressed against the sides Lof the book, andY tliedescribed plan 'of rst scoring the wrapper and then progressivelyfolding it up and pressing its sides into place wellaccomplishes thisobject, sothat the ilnal steps of t-he wrapping operation will turn outa satisfactorily wrapped product free of wrinkles and looseness. Anysubstantial drag against the wrapper during -the applying operation'would tend to displace it. The fact that the lbelts I3 travel at asomewhat greater speed than the travel of the book, but in an upslantingdirection,

the actual forward component equalling the speed of the book, preventsany wrinkling action. Each side of the wrapper is folded, pressed andsmoothed snugly upwardly into place by an action which is the equivalentof that of a straight edge or ruler held at an incline and rubbedvertically upwardly in relation to the book, while partaking of theadvancing motion.

As already explained the side conveyor belts 45 and the under beltconstitute a preliminary conveyor group which terminates in advance ofthe wrapper upfolding operation, to accommodate the diagonal smoothingbelts ||3. Beyond the diagonal belts is provided the second or rightgroup of conveyor belts, namely side belts |25, upper and lower at eachside, and an underneath belt |40 to be described. 'Ihe side belts |25pass around horizontal pulleys |26 at their left ends and larger pulleys|21 at their right. ends, as seen in Figs. 1, 2 and 3. Throughout thelength of each belt |25 is system of pressure pulleys or rollers |28,seen also in Figs. 8 t'o l1, holding the belts up to the path of thebooks at each side, these pressure rollers, upper and lower, beingmounted on brackets |29 attached on top of the table 23.

The conveyor belts |25 are driven by means of their right pulleys |21,the two pulleys at each side being mounted on a vertical shaft |3|extending downwardly into the base column 25, each shaft being providedwith a worm Wheel |32 engaging a worm |33 on a horizontal shaft |34extending outwardly froin the column and having a sprocket wheel drivenby a sprocket chain |35 from a corresponding sprocket wheel on the mainshaft 30.

The advancing books carrled along between the side conveyor belts" |25rest upon an under belt passing around a` left pulley |4| and a. rightpulley |42, the belt traveling in a slight depression or recess in thetop of the table, as indicated in Fig. 8, 'and driven as follows. On thesame shaft withthe right pulleys |42 is a smaller pulley |43 connectedby a belt or chain |44 with a pulley |45 on a. cross shaft |46 turningin a base bracket |41, the shaft |46 carrying also a worm wheel |48driven by a worm |49 on a worm shaft |50, which carries also a pinion|5| meshing with a pinion |52 mounted on the main shaft 30. As beforestated, the proportions of the several drives are such that all of theconveying elements will advance rightwardly with speeds correspondingwith the predetermined speed of travel of the book. As each book isdelivered rightwardly by the travel of the side conveyor belts 25 andthe under belt |40 they may be discharged into any kind of receptacle.Conventionally there is shown an outfeeding conveyor |56 in the natureof an apron traveling slowly to the right. As each book f emergesedgewise, a flapping device |51 of a fixed nature may operate to turneach book over forwardly so as to lie upon the book previouslydelivered. This is shown as a curved or warped deflector plate |51. 60After each book with wrapper emerges from the upfolding and smoothingdevices described the wrapper is lrst preferably 'scored to facilitatesubsequent tucking and down folding operations.. The scoring tool |60for producing two score lines on the rear wrapper flap W' and two on thefront wrapper flap W2 is shown in Figs. 1, 8 and 13-15. This tool may beinterchangeable for different thicknesses of book, and the cooperatingparts may be correspondingly adjustable. .The scorer is shown ascomprising upper and lower rear scoring blades |6| and upper and lowerfront scoring blades |62, the formerl being spaced vertically apart by-adistance `equalling the entire thickness ofthe book, while the latterare spaced apart a smaller distance due to the fact that the front fiapW2 is to be tucked in at about the center of the book as appears in thesubsequent Figs. 9 and 10. This entire assemblage may be gaged orpositioned vertically by the book itself, being mounted as will bedescribed in a floating manner so as to rest resiliently upon the upperedge of the traveling book. i I

The mountings of the scoring tool |60 may be as follows. It is shown asattached to a sheet metal shank |64 of an inverted U-shape, the frontleg depending above the book and carrying the tool, while the rear armdepends to the rear thereof, where it is mounted by slot and pin devices|65 for vertical sliding motion at the front of a plate |66 which isxedly mounted at the ,top front part of a fixed bracket |69 upstandingfrom the table 23. As appears in Figs. 13 and 14 there are right andleft toggle pairs |61, each connected above to the plate |66 and belowto the tool shank |64, with a connecting spring |68 pulling upon thefloating joints of the toggles. By this arrangement the action of thespring is to supplement gravity and resiliently thrust down the shank|64, thereby yieldingly holding the scoring tool upon the edge" of thebook. For the wrapping of a given batch of books the described devicesmay be lifted manually to admit the first book, or the entire device maymanifestly be vertically adjusted for books of different width, and asseen in Fig. 13 the initial end of the scoring tool may be curvedupwardly to avoid conflic with the advancing' book; and the final ordelivery end may either continue straight to the end, or be curvedupwardly as shown, at a point removed from Ythe scoring operationso faras to cause no conflict therewith.

The effecting of the two scoring marks on eac wrapper flap may be by thescoring blades |6| an |62 respectively in cooperation with rear an frontscoring bars |1|, these being shown as-lon gitudinal members,substantially as long as book, each having a cushioned face |12 composefor example of rubber, the two scoring bars be ing adapted to be movedsimultaneously towar each other, to press the opposite flaps of thwrapper against the scoring blades. This i shown as performedintermittently. in such manner that the scoring bars vpartake of theforwar travel of the books, thus permitting continuo of the scoring bars|1| is shown as mounted di rectly upon two crank pins |13 turning inunison, the crank pins upstanding from crank disks |14 mounted at thetop ends of vertical shafts |15, which shafts extend downwardly throughbearings |16. By this arrangement the two scorin bars move in constantparallelism, each of the describing a circular path and the two of themconverging upon the wrapper and scoring tool intermittently as thecranks |13 move around their.circular paths, the blades impressing the lwrapper fiaps into the resilient faces |12 and so leaving creasesdetermining thev subsequently folding actions.

The two crank shafts |15 at each side of the machine may beinterconnected by sprocket wheels |11 thereon engaged by a sprocketchain |18, and

variations in book thickness an arrangement may be employed similiar tothat shown in Fig. 4 in- I described mechanism one of the shafts |15 may,be extended' downwardly to where it carries at 'lits lower end abevel-gear. lilfe'ngaginga complementary bevel gear |8| on'a crossshaft, whichA shaft-alsocarries a sprocket wheel 'drivenjby la sprocketchain |82 from a correspondingr sprocket wheel onthe shaft-54 derivingits rotation from the main shaft' 430.

The nextoperation is the bending inward and downward and tucking betweenthe sheets of the book the front ap W2 of the .wrapping sheet. Themechanism for this preferably operates progressiveIy by reason of thetravel of the book and wrapper, and is shown in Figs. 2, 3 and 9 as atucker plate or blade |85 mounted adjustably or oatingly in properrelation to the top edge .of the traveling books. The tucker |85 may beof the general nature of` a tucking implement on a sewing machine, beingcomposed of shaped `or twisted sheet metal, the rst or left-end |86extending high up so as to overreach the book and wrapper, and fromthere toward the right the tucker being of progressively more and morebent contour until, at its right end |81, it is of inverted U crosssection, the rear leg occupying the` space between the separated partsof the book.. This. iixed tucker blade therefore serves both to open upand separate the leaves of each advancing book into two portions, whichis easily effected since this part of the book is loosely held, andprogressively to bend over and downwardly between the leaves of the bookthe front flap of the -at the front upper margin of the rear wrapper apW' during travel of each book. Conventional mechanism therefor is shownin Figs. 2, 3` and 10 wherein a pasting or gluing disk |94 is shown asapplying adhesive to the wrapper flap at a properly adjusted distanceabove the book, near the edge of the ap. 'I'he gluing disk |94 isopposed by a roller |95, which may be an idler roll. The

disk is shown partly enclosed in a glue vessel 96, projecting throughthe rear side of the vessel with a close fit to prevent escape ofadhesive. The glue roll is driven, being shown mounted at the lower endof a driven shaft |91, the upper end of which carries a helical gear |98engaged by a similar gear |99 on a cross shaft 200 whichshaft carriesalso a sprocket wheel 20| driven by a chain 202 from a similar sprocketwheel on the shaft |46 already described. Y

The next operation is the bending and folding over and down` ofthegluedrear wrapper flap W' and 'applying its glued margin to the front side ofthealready tucked in front wrapper flap W2. For this purpose there isshown in Figs. 2, 3 and 11 an over-folding plate or blade 205 analogousto the tucker |85 and similarly adjustable or floating in relation-tothe book. The over-folding plate 205 h as a high first or left .endf206which engages and starts the deflection of the wrapper, the plate beingof twisted character and its right end terminating with a lowerportion201 whereat the ap has been completely turned, down and thrust againstthe front side .of the book, the plate having an inverted U-shape atthis point. By this arrangement as each book A travels.through this partof the machinefthe wrapper flap is progressively turned over and presseddown into place, Ihaving been already scored at the two ypointsrequisite for making sharp bends and affording' a neat appearance to theproduct. TI'he,0ver-folding"plate 2051s shown mounted at the top en'd ofa special bracket 208 which for convenience may be mounted on one of the.brackets |29 already mentioned l The last step before discharge istheapplying of pressure to the opposite sides of the book adjacen?I tothe line of adhesive vso as to seal `nall'y the wrapper upon .the book.4For this purpose there is shown in Figs. l, 2 and 12 a pair of oppositepressure belts 2|3 of short extent,'operating beyond the over-foldingdevice 205 to apply progresslve pressure upon eachbook until itsdischarge. The opposite belts 2|3'pass around large right hand pulleys214 mounted at thel top ends of the shafts |3| already mentioned.Mounted loosely upon the top of said shafts ar'a pair of swingablebrackets 2|5 extending leftwardly and v each carrying a lef-t handpulley 2 I6 around which also the corresponding pressure belt travels.The two swingable brackets 2|5 may be secured or clamped in theiradjusted positions as shown or they may be 'drawn-together resilientlyby an overhead spring 2|8 or analogous means, to hold them pressingfirmly against the opposite sides of the advancing books. Beyond thesealing or adhesive pressure device the wrapped books W B pass inprocession to the discharge and outfeed devices already described.

The complete machine hereof and the successive operations may be summedup as follows, it

being understood that the invention includes not only the completecombination, butl subcombinations and individual mechanisms. The machinecomprises means VJfor causing continuous straightline travel edgewisevthrough the machine of a processionof books; the travel being straightat least from and after the point of assemblage or meeting of the book Band wrapper W; the word books intended to include analogous objects.Means for feeding a processionv of wrappers and -assembling them withthe successive books during travel lso that the bottom longitudinal edgeof each book, in this case the back of the book, is

positioned upon the middle part of the correspondng wrapper. For ease ofdescription relative terms such-as top, bottom, up, down, vertical, andhorizontal are employed, without however intending them as limitations,since in many cases the arrangements may be altered or reversed withoutchanging the principles. Means, as ,disks 99, for longitudinally scoringeach wrapper during feed to form parallel score marks corresponding tothe side corners of the bottom'v edge of the book. This scoring is shownas performed before the wrapper meets the book, but might equally wellbe performed just after the wrapper meets the book by scoring means or'blades locatediadjacent tothe' corners of the book. Means, as belts i3,for thereafter upfolding the side flaps of each wrapper during traveland causing the same to li'e flatly against the side facesl of thebookwith the top edges of the iiaps, or at least one of them, above thetop edge of the book. Means, astool |60 and bars |1|,

for'thereafter during travel scoring each wrapper flap alonglongitudinal lines corresponding to the later folding of the respectiveiiaps;.this scoring being preferably performed at this stage rather thanat the same earlier stage with the middle scoring of the wrapper. Means,as plate |85, for

. thereafter during travel folding over one of the wrapper aps andtucking it down between the components or pages of the book; this beingpreferable to folding it outside of thebook, and affording a lockingbetween the book and wrapper. Means, as disk |94, for thereafter duringtravel applying .adhesive to one wrapper flap along a longitudinalsealing line; this being shown as placing a stripe of glue along theinner top margin of the unfolded wrapper iiap, although it might equallywell be applied at the proper sealing line along the already foldedflap. Means, as plate 205, for thereafter during travel folding over anddown the second wrapper flap and applying it to the rst ap for sealingby such adhesive. Finally is the means, as belts 2l3, for applyingduring travel sealing pressure upon the second wrapper fiapat thesealing line, so that the product is then in suitable condition fordischarge. The straightline book travel may in some cases need to bemodified preceding the wrapper folding etc., for example, in the case ofy a thin pamphlet which is required to be first 1.
